Co-Founder & Backend Engineer
location_onBudapest, HU
Tamas leads the Python backend, data layer, and security review at CZ Dev. Day job: vulnerability threat management analyst at Citi, where he built the GEM Dashboard in two months, shipped the Firewall and Load Balancer Vulnerability Dashboard solo, and wrote the email composer that cleared Apache Tika XXE and Oracle HTTP Server RCE L0 incidents inside their 48-hour windows, replacing a 4-hour manual mail-merge with a 12-minute pipeline. Before Citi: on-call for critical OpenStack infrastructure at Ericsson (95% on-time delivery, 90% queue utilization on concurrent cases) and reporting under intra-day SLAs at BlackRock (200+ daily reports, 30% direct ticket reduction). At CZ Dev he ships VitalRegistry v1 and v2, KEV Explorer, and Advisory Composer, and leads security review across the portfolio. Stack: Python, TypeScript/React, Firebase. BSc in Business IT, Budapest Business School.
